The practice of sending a person or group of people to target someone you don't like, usually via raiding, doxxing, toxxing/reporting, etc. Plural is to be sicc/sicced on.
I saw Joel siccing XXX_SKIBIDISIGMA_XXX, Xiuhcoyotl and Imperator on Kiwifarms after what happened with them on the old Schlog.
Get the Siccing mug.
